I installed the MyFiles block, kept the default values for the configuration, and I can access the MyFiles block in Moodle. However, when I upload a file, the system quickly displays a confirmation (for less than half a second), then brings me right back to the MyFiles screen. However, no files or web links are shown. I confirmed that the files are located on the server, so the files are indeed uploading... it appears to be a problem with Moodle not understanding that I have uploaded files and therefore not displaying them. Any ideas why this may be happening and what I can do to fix it?
